v Application filed April 2&1893. Serial No. 472,236- (No modhl) To all whom it may concern:

Be it known that we, WILLIAM GWYNN, Jr., and DENNIS SPENCER, of Napa, inthe county of Napa and State of California, have invented J certain new and useful Improvements in Tubs; and we do hereby declare the following to be a full, clear, and exact description of the inven- B is aifalse-bottom which thr oughout its length is parallel 'with bottom a and the same 6 has a continuous flanged edge I) which is attached to the edges of said bottom a; Upon this flan ged edge is a beveled strip 1). Through 'opcningsin one end of bottoms a and B are passed valved pipes bi-b for the admission f of hot and cold water onto. the false bottom, and between said pipes is an. overflow pipebr C is a pipewhich. opens at d into onesid t of bottom a, and. its outer end is connected to a perpendicular pipe 01 inclosedin a hot-air 6o .7 flue or jacket D. This pipe C supplies shot 7 air or steam, or hot-water, to the chamber (2 tion, such as will enable others skilled in the art to which it appertains to make anduse the same. y

This invention contemplates certain new and useful improvements in tubsfor bathing or washing pur oses, and it has for its object 'to provide a .tu which can be readily heated and whereby the water therein will be maintained at a high degree of temperature.

The invention comprises a tub having a false-bottom or lining forming a continuous 2o I the outer wall or bottom and likewise an exit chamber for steam or hot-air or hot-water,

which is fed thereto through an opening in i in said wall or b'ottomto complete the circu-. vlation, and means for supplying hot and cold water to said tub "and also to permit the discharge thereof and the discharge from said chamber. T The invention also comprises the details of construction, combination and arrangement of parts,substantially as hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings:-Figure 1 I 'is' a vertical longitudinal sectional view of our improved tub. Fig. 2 is a transverse sectional. view on line mw,'Fig. 1. Referring-to the drawings, A designates the tub, proper, a'the continuous bottom; sides (and ends thereof; 0. legs extending from the formed between 'andbytheiwo bottoms of the tub. An exit-pipe E opensinto one side of bottom a, and isfdesigned tocomplete the 6 circulation of steam, or; serveflts an. exit for hot air. Inthe bottom B is an outlet opening'e directly coincident with pipe 0, and the latter and said opening are normally closed bya tapered plug F. By removing this plug the water inthe tub and in the chamber between the two bottomscan be readily permitted to how out.

a The advantages of our invention are appar-' ent. It will be seen that by admitting steam or hot-air,-. or hot-water, ifpre'ferred, into the chamber between the real and false bottoms the water contained in the-tub, proper, wills be maintained at a high degree of tempera- 1 It will also be seen that a complete circulation for the conturefor along period of time.

fined steam is obtained, and that the contents.

of the tub and chamber can be'readily'drawn ofi3. A tub-thus constructed is inexpensive and the advantages attained are of. a superior latter; and a an outlet pipeleading from an wopening in the bottom. Inone end of bottom H q. are two valves a ,'c t ,.the former being used for the admission of air to preventthe formation of avaeuum by any sudden condensation of the steam in the chamber between the 5 real and false bottoms of thetub; while the --la,t t'er is usedas a vent or. outlet'tp'relieve any enitraordinary pressure of steam in said {"chamber. e

tinnous bottom a provided at one end with air and vent valves, the exit pipe connected to said bottom, the false-bottom parallel with 5 said bottom a forming a heating chamber and having a hole directly above said exit-pipe,

the plug, the steam or hot-air supply and outlet pipes opening into one side of bottom a and communicating with said heating Chem- 10 her, and the water-supply pipes extending through said bottoms at one end, substan- -tially'assetforth. w f
